SPECIFICATION forming part of Letters Patent NO. 672,295, dated April 16, 1901.

Application filed $epteniher 27, 1900. Serial No. 31,235. (No model.)

To all whom it may concern:

Be it known that I, THOMAS STEVENSON, a subject of the Queen of Great Britain, residing at Victoria, British Columbia, Dominion of Canada, have invented certain new and useful Improvements in Caps and Filling Devices for Fountain-Pens, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to caps andfilling devices for fountain-pens; and the object thereof is to provide an improved combination cap and filling device ofthis class which is designed to serve both as an ordinary cap for the pen or point of a fountain-pen and which is also designed as a device for filling the reservoir of the pen.

The invention is fully disclosed in the following specificatiomof which the accompanying drawings form a part, in which-- Figure 1 is a side view of one end of the stock of a to untain-pen,showingmyirnproved combination cap and filling device; and Fig. 2, a similar view showing the combination cap and filling device in section.

In the drawings forming part of this specification the separate parts of my improvement are designated by the same reference characters in each of the views, and in said drawings I have shown at a the tubular stock and reservoir of an ordinary fountain-pen, said stock and reservoir being broken away at one end and being provided at the opposite end with a pointed or tapered section or member a which may be detached, if desired, and through which in practice the ink passes to the pen b. The parts a, a and b may be of the usual or any desired form and construction, and it will be understood that if the member a is not detachable from the stock and reservoir the opposite end of said stock and reservoir will be detachable. I also provide a combination cap and filler comprising a tube a, which is adapted to be mounted on the tapered member a of the stock and reservoir, as clearly shown in the drawings, and this tubular member is provided at one end with a reinforcing band, rim, or rib c and with a longitudinal slot 0 and is tapered at the opposite end, as shown at c, to form a nozzle and provided at said end with a port or passage 0 and mounted on the tube a is a sliding band d, provided with pins 01 which pass through the slots 0 and which are connected with a slide f on the inner side of the tube 0, said slide being provided at its outer end with a piston-head g, around which is placed a packing-ring g and the piston-head g is provided with a pin g which passes into the port or passage 0 at the nozzle end of the tube 0 and is adapted to close said port or passage. The parts 9 and g constitute a piston-head and may be of any desired construction and may be formed integrally with or connected with the slide f, which constitutes the piston-rod, and the pin 9 may be also formed integrally with the piston or may be formed separately and connected therewith. The tubular attachment 0 as thus constructed constitutes, as will be seen, a detachable cap or cover for the pen and also constitutes a pump,operating in the manner of asyringe, for filling the stock and reservoir a, and said pump is operated by holding the tube 0 in one hand and operating the sliding band 01. In this operation the nozzle end 0 of the tube 0 is held in the ink, and as the band d is moved in the direction of the opposite end of the tube 0 the said tube will be partially filled with ink, and the ink may be forced out into the stock or reservoir a by moving the band 01 in the opposite direction.

This device is simple in construction and operation and perfectly adapted to accomplish the result for which it is intended and is also comparatively inexpensive, and by means thereof the usual tubular cap with which fountain-pens are usually provided is also made to serve as a pump for filling the reservoir or stock.

Having fully described my invention, I claim as new and desire to secure by Letters Patent able point-covering cap, and means. within the cap for pumping fluid into the cap when removed from the pen,substantially as shown and described.

2. A fountain-pen provided with a tubular cap having a slot in one side, and open at one end, and provided with a nozzle at the opposite end, said tube being also provided with 1. A fountain-pen provided with a detach- IOO asliding band whiohis mounted thereon, and I with a piston which is in operative connection with said band through said slot, substantially as shown and described.

3. A combination cap and fillingdevioe for fountain-pens, comprising a tube open at one end,and provided at the other with a nozzle, said tube being also provided in one side with a slot, and a sliding band mounted thereon, and a piston mounted therein and in operative connection with said band through said 1 slot, said piston being also provided with a pin which is adapted to close said nozzle, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name,'in presence of the subscribing witnesses, this 20th day of September, 1900.

THOMAS STEVENSON.
